Roofing materials mainly play a role in waterproofing, heat insulation, and seepage prevention; then, what are the commonly used roof waterproofing and heat insulation materials in China? Don't worry, in order to let you know all aspects of roof waterproofing and insulation materials , this website Xiaobian allows you to spend the least money to decorate the most beautiful home. What are the waterproof roof insulation materials? Roofing waterproof material There are many roofing waterproofing materials. Here are some of the new types of roofing waterproofing materials. 1. Biaxially oriented polyvinyl chloride (PVC) sheet: Biaxial stretching means that at a specific high temperature, the polyvinyl chloride sheet is stretched by 100% in two directions perpendicular to each other, so that the molecular chain of the PVC sheet is re-ordered. The arrangement, which greatly increased the cohesion of its molecules, significantly increased the physical and mechanical properties of the board. Before stretching, the UV protection layer and the PVC layer are co-extruded, and then the biaxial stretching process is performed. This ensures that the UV protection layer is evenly and densely covered on the surface of the sheet, and it is completely integrated with the PVC layer. . This process overcomes the weaknesses of ordinary PVC sheets in terms of strength and durability, and becomes a high-quality material. Use range: biaxially stretched PVC board is divided into two kinds of colored and colorless. It can be used for waterproofing of large public buildings, industrial plants, stadiums, sports halls, flower planting and aquaculture greenhouses, shelters, pavilions and other roofing; it can also be used for indoor screens, soundproof curtain walls, safety shelters, walls, guardrails, partitions of houses. Wall partitions, site safety barriers, and tunnels. 2. Co-extruded sandwich foamed polyvinyl chloride tile: The production and use of co-extruded sandwich foamed polyvinyl chloride tile has just started in China. Due to high production efficiency, reliable quality, reasonable price, beautiful appearance, and waterproof material on the roof. In the sudden emergence of the army. Its shape is like a wavelet asbestos tile, the length can be determined according to needs; another shape is similar to the shape of the European tile, after the width is determined, the length can be determined according to need, and the color can be varied. Scope of use: It can be used for slope roofs of public buildings, residential buildings, factory buildings, etc., as well as interior and exterior decoration and partitions of buildings. Tile thickness 2-20mm (current production is mainly 3-5mm), width 880-1040mm, length can be made on request. The color of the tiles can be formulated in the raw materials, or it can be painted after extrusion. 3, rigid foamed polyurethane: rigid foaming polyurethane for roofing projects, both for waterproofing and insulation. Use range: rigid foamed polyurethane can be used in a variety of roofing projects. The base used is mainly concrete cast-in-place slabs or precast concrete slabs and cement mortar screeds. There is a separate field foaming polyurethane, both as a waterproof layer, but also as insulation; some as one of the waterproof layer, but also the insulation layer, and waterproof membrane or waterproof coating composite; also waterproof coating, waterproof membrane, hair Polyurethane foam 3 kinds of materials together form a waterproof insulation layer. 4. Polycarbonate sheet: Polycarbonate sheet is a very good architectural decoration and waterproof material for roofing. In recent years, it has been used in many large-scale public buildings and public facilities in China. Scope of use: It can be used for interior and exterior decoration of roofs, shelters, walls, partitions, curtain walls, etc. of buildings, as well as greenhouses, public telephone booths, billboards, light boxes and display arrangements. 5, color profiled steel plate: color profiled steel plate in the factory or construction site press molding, the steel plate used for pre-coated steel products, high-speed continuous unit on the chemical pretreatment, the initial coating, fine coating and other processes made. The coating quality is more uniform and stable than the surface quality of a single-piece sprayed or brushed metal. The color coated steel sheet has excellent decorative, formability, corrosion resistance, strong coating adhesion, and can maintain bright color for a long time. Scope of use: Suitable for building roof panels, wall panels, especially for large-span factory buildings, warehouses and mobile home building roof, enclosure structure. The thickness of the veneer of the color press composite board is generally 0.6-0.8mm. The board peak height is 15-130mm, the board width is 600-900mm (effective width), and the length is determined as needed. The roof structure consists of a lightweight beam and a girder, and the plate and girder are anchored by screws. Color pressure composite panels can also be combined with thermal insulation materials. The thickness is generally 0.6-1.5mm. The peaks are almost the same as the veneers, and the width is about 1m. The length is determined according to the requirements. The structural layer of the roof is from top to bottom: color-pressed composite panel + mineral wool-aluminum foil + wire mesh + silencing cloth + honeycomb aluminum panel + purlins + light steel rasps. The board and the board, the board and the purlins are anchored by screws. There is also a relatively simple structural layer, the practice of color pressure composite board - mineral wool + aluminum foil - purlin + truss. 6. U-shaped glass plate: U-shaped glass plate is a new type of architectural glass that is commonly used abroad. It is produced in a continuous manner after being rolled and then molded. It is named after its U-shaped cross-section. U-shaped glass has the ideal light transmission, heat insulation, heat preservation, high mechanical strength, convenient construction, and unique architectural decoration effect. Scope of use: Mainly used for building roofs, enclosure structures, non-load-bearing walls, internal partitions, etc. When used as wall material and roofing material, it can be used vertically, horizontally and obliquely. It can be used for single-row, double-row or other various types of installations. It is a multi-purpose building component profile. 7, thermal insulation waterproof track panel Scope of application: One type is used for the roof of the grid (steel grid structure and other small-span steel truss supporting use); the other is the use of large-span roof (>4m) and steel roof truss. The development of the board is in the direction of multi-function (combination of waterproofing, waterproofing, decoration, and use of functions), the development of waterproof materials to the composite of waterproof technology (combination of different materials such as color plates and glass), and the development of the roof form to the complexity. Roof insulation Roof insulation materials should be selected lightweight, porous, thermal insulation material with a small thermal conductivity. According to the characteristics of the finished product of the insulation material and the construction process, the insulation material can be divided into three types: bulk material, on-site pouring mixture and plate material. Bulk material and cast-in-place insulation have good plasticity and can also be used as a substitute for slope-seeking layers. (1) Plate type thermal insulation materials: There are mainly polyphenylene plates, aerated concrete plates, foam plastic plates, expanded perlite plates, and expanded vermiculite plates. This material has the advantages of quick construction, good insulation effect, and avoidance of wet operation. It is widely used in engineering. If possible, it is better to use two or more layers to form a heat insulation layer and handle the joints between the plates to avoid thermal bridges. (2) On-site pouring type thermal insulation material: it is made of bulk material used as aggregate, mixed with cement or lime cement, plus appropriate amount of water, and in-situ cast insulation layer. This kind of insulation layer has good processability, but after the insulation layer is in place, it is still in a wet state, and it is unfavorable to heat insulation. It is often necessary to provide a vent in the insulation layer to emit moisture, which is troublesome in construction. (3) Bulk material insulation materials: There are mainly expanded perlite, expanded vermiculite, and slag. Because the bulk material is easily affected by wind and other factors during construction, it is not easy to form and it is difficult to construct, and it is rarely used in practical projects. The above information about roof waterproofing and thermal insulation materials is briefly introduced here and I hope to help you. For more information, please visit this website. Stay tuned.
